Equipment Used
|
|
|
Purpose
|
|
To study seamount ages and basalt chemistry in order to better
|
|
understand the long term history of the South Pacific thermal anomaly.
|
|
|
Information to be Derived
|
|
Sample descriptions, detailed chemical and mineralogical analyses of
|
|
bulk Fe-Mn crusts and individual crust layers, and major oxide compositions and
|
|
mineralogy for substrate rocks.
|
|
|
Summary
|
|
13 NW Pacific seamounts and guyots were dredged during the Tunes 6
|
|
cruise. A total of 35 dredges were attempted and 23 recovered Fe-Mn crust
|
|
samples and substrate rock. One or two dredge hauls recovedred samples from most
|
|
guyots, however, Vlinder and Batiza Guyots yielded five and four dredge haul
|
|
recoveries, respectively. Minor additional bathymetric surveys were conducted
|
|
during Tunes 6.
